Helping your infant or toddler develop good dental habits is one of the best head starts you can give them toward optimum oral health. But even after they’ve matured enough to handle hygiene tasks without you, they still need your guidance.

This is especially true in the “tween” and teen years. Although they’re beginning to flex their independence muscles, they’re still vulnerable at this age to peer pressure urging them to try things that, among other outcomes, could hurt their oral health.

Here are 3 areas where your input and guidance could save your older children and teens from oral health problems.

Sports activities. As children mature, they may also become involved with various physical activities, including contact sports. Years of diligent hygiene and dental care can be undone with one traumatic blow to the mouth. You can help avoid this by urging your child to wear a mouth guard during sports activity. While there are some good choices on the retail market, the most effective mouth guards are custom-created by a dentist to precisely fit your child’s mouth.

Oral piercings. While expressions of solidarity among young people are popular and often harmless, some like oral piercings and their hardware could potentially damage teeth and gums. You should especially discourage your child from obtaining tongue bolts or other types of lip or mouth hardware, which can cause tooth wear or fracture. Instead, encourage them to take up safer forms of self-expression.

Bad habits and addictions. A young person “spreading their wings” may be tempted to dabble in habit-forming or addictive activities. In addition to their effect on the rest of the body, tobacco, alcohol and drugs can have severe long-term consequences for oral health. Unsafe sexual practices could lead to the contraction of the human papilloma virus, which has been linked to oral cancer in young adults. Be sure your teen understands the dangers of these habits to both their oral and general health—and don’t hesitate to seek professional help when a habit becomes an addiction.
